ADJUSTABLE WORK-SUPPORT.

Specification of Letters Patent.

Patented Dec. 12, 1911.

Application filed February 17, 1911. Serial No. 609,078.

T 0 all whom it may concem:

Be it known that I, ARTHUR W. ANKn-NY, a citizen of the United States,residing at Indiana, in the county of Indiana, State of Pennsylvania,have invented certain new and useful Improvements in AdjustableWork-Supports; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to an improvement in article supporting bracketsgenerally, and more particularly to bracket attachments for drawingdesks.

The principal object is to provide a bracket for drawing desks forsupporting objects to be drawn.

Another object of the invention is to provide a bracket for the purposedescribed which can be adjusted to various heights and shifted tovarious angles in order to properly position an object for an artist.

A further object of the invention is to provide a device of the classdescribed which can be easily assembled or disassembled and when in theformer position will be securely retained against accidentaldisplacement.

A still further object of the invention is to provide a device of thecharacter described which is extremely simple in construction, iscomposed of a minimum number of parts, and is therefore cheap tomanufacture.

lVith these and other objects in view, the invention consists in the.construction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe appended claims, may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a perspective view showing my inventionapplied to a drawing desk, Fig. 2 is an enlarged front elevation of theplate, Fig. 3 is an enlarged rear elevation of the plate, Fig. 1 is asectional view of the plate taken on the line 11 of Fig. 2, Fig. 5 is anend view of the plate showing a book supported thereby, Fig. 6 is anenlarged sectional view through the corner fastening of the bracket,Fig. 7 is a detail sectional view through one of the flower-stemopenings, Fig. 8 is a perspective view of one of the spring-engagingclips, Fig. 9 is an elevation of the clamp showing the adjusting meansfor the rod, and Fig. 10 is a vertical sectional view taken on the line1010 of Fig. 9.

Like reference characters indicate corresponding parts throughout theseveral views.

Referring to the drawings the reference numeral 5 designates a drawingdesk of any suitable construction and having a top 6, the edge 7 thereofpreferably overlapping the contiguous side wall. Attached to the saidedge 7 of the desk is a clamp designated as a whole by the referencenumeral 8. This clamp is preferably formed of cast-iron and consists ofopposed leaves 9-9 and a connecting end portion 10. The leaves 9 aredisposed on opposite faces of the top and are fixedly secured thereto bya clamping screw 11 which is carried by one of said leaves. Centrallyformed in the connecting portion 10 is an opening 12 and disposed withinthis opening is a secondary clamping member 13, the inner end 14 thereofpreferably frusto-conical and the inner wall of the said opening 12 iscorrespondingly shaped. Extending forwardly of the connecting portion 10and integral with the portion 1 1 is a head 15 having an elongatedopening 16 formed therein. Movably secured to the outer end thereof is aclamping bolt 17. It will be observed that this secondary clampingmember 13 is rotatable and is disposed at right angles to the connectingportion 10 of the primary clamp. Formed in the outer face of theconnecting portion 10 is a plurality of grooves 18 which radiallyproject from the opening 12 thereof.

Disposed within the opening 16 of the secondary clamp is a supportingrod 19 and this rod can be shifted to or fro and retained in anyadjusted position by being fitted in any one of the said grooves 18 andretained therein by the clamping bolt 17. It will also be observed thatupon releasing the bolt 17 the said rod 19 may be adjusted to differentheights as may be desired. The upper end 20 of the rod 19 is reduced andpreferably rectangular in shape.

Extending laterally from the upper end of the rod 19 is a bracket arm 21which is provided at one end with a rectangular opening 22 adapted toreceive the reduced end 20 of the said rod and at its other end with areduced elongated circular portion 23.

The invention further comprises a brace 24 of any suitable design whichis provided with projecting spurs 25-25, said spurs being preferablydisposed at right angles to' each other. These spurs are detachablyseated within corresponding openings 26 and 27 formed in the arm 21 androd 19 respectively. This brace it will be observed is detachable and byreason of the spurs being arranged at right angles a very eifectivebrace is thereby produced. Formed in the arm 21 are spaced openings 28.These openings may be disposed at various angles but they are preferablydisposed vertically. These openings are oppositely tapered, and.associated with each opening is a flat spring clip 29having a pointedend 30. The said clip is secured to the arm by any suitable means andthe pointed end 30 thereof projects into the opening 28 and is adaptedto pierce the stem of the flower or the like and thereby secure the samein position. It will be observed at this point that by forming theseopenings in a tapered manner the stem of a flower can be easily guidedthereinto and that by reason of these said openings being oppositelydisposed the flowers may be retained above and below the said arm as maybe desired.

The invention further comprises a plate or support designated as a wholeby the numeral 31. This plate is preferably formed of sheet metal and isrectangular in form. The plate consists of a body portion 32 and upperand lower portions 3333. Inasmuch as the end portions together with thehereinafter described attachments are identical the description of onewill suffice. The end portion 33 is hinged to the body 32 by aknuckle-joint 34 and pin 35. The adjacent knuckles of the hinge arerespectively provided with abutting shoulders 36 by means of which therearward movement of the end pieces 33 is limited. In other words theseshoulders prevent the said end pieces from moving rearwardly out of theplane of the body portion 32. Extending inwardly from the outer edge ofthe piece 33 is a centrally disposed slot 37, thereby forming spacedears 38. The outer or front edges of the ears 38 are bent to form alinedsleeves 39 and disposed within the said sleeves is a pin 40 which ispreferably formed of steel, said pin extending across the said slot 37.

A spring wire 41 is disposed longitudinally of the piece 33 and insubstantial alinement with the connecting wall 42 of the said slot 37and is secured to the piece 33 by any suitable fastening means. Disposedwithin the slot 37 is a movable plate 43, the outer edge 44 thereofbeing bent to form a bearing sleeve which is positioned on the pin 40.The opposite edge is also bent to form a sleeve 45 which is adapted toengage the spring rod 41.

A wire clip 46 is bent to form an elongated loop 47 which normally liesagainst the body portion 32 and tends to keep the pieces 33 in alinementtherewith. This spring clip eX- tends centrally from the loop around theplate 43 and thence forwardly of said end pieces to form a finger-piece48 by means of which the said block 43 can be elevated as shown by Fig.5 of the drawing.

Secured to the back of the body portion and adjacent the end pieces 33are springs 49 one end of each spring being secured to the said bodyportion and the other end 50 being bent at right angles for normallyengaging the contiguous piece 33. Thus it will be observed that when thepieces 33 are swung forwardly the end portions 50 of the springs willengage above and below the respective pieces and thereby form supportsfor the same.

Secured to the back of the plate is a suitable bearing boX 51 which isadapted to receive the reduced end 23 of the bracket arm 21. By means ofa wing-bolt 52 the said plate can be secured at various angles as willbe readily understood.

From the foregoing it will be observed that an artist will desire tohave an object suspended in an inverted position. lVhen this is desiredthe upper spring clip 46 is employed. lVhen, however, it is desired tosupport an object in its normal position the lower clip 46 is employed.Articles having considerable thickness, such as books or the like, canalso be retained by this plate. When such articles are employed thelower piece 33 is swung forwardly and retained therein by the clip 49 asbefore mentioned, and the finger piece 43 depressed thereby elevatingthe block 43 and the loop 47. The article can then be placedintermediate the loop 47 and the body portion 32 of the plate and thesame will be retained therein.

Whenever it is desirous of swinging the bracket arm 21 the clamping boltof the secondary clamp can be loosened and said arm swung to the desiredposition. Whenever it is desired to dispense with the use of the bracketthe said vertical arm can be lowered, together with the bracket in sucha manner that the latter may be positioned directly upon the desk. Thusin this position the bracket and rod are both entirely out of the way.

What is claimed is 1. An attachment for desks comprising in combination,a clamp, a secondary clamp rotatably carried thereby, a rod adjustablysupported by said secondary clamp, a bracket-arm detachably supported bysaid rod, said arm being provided with a plurality of taperingstem-receiving openings,

and spring stem-penetrating clips carried by the arms and having pointedends projecting into said opening.

2. An attachment for desks com rising in combination, a clamp consistingo opposed leaves and a connecting end portion, said portion beingprovided with a centrally disposed opening, the inner end thereof beingflared, said connecting portion being also provided with a plurality ofgrooves projecting radially from the said opening, a secondary clampdisposed Within the opening and having an inner end corresponding inshape to the inner end of said opening and having its outer endprojecting forwardly thereof and provided with a head having anelongated opening, a rod disposed within the opening of the head, meanscarried by the head for securing the rod in any of the grooves of theconnecting portion of the first mentioned clamp, a bracket-arm supportedby said rod, and an article support carried by the arm.

3. An attachment for desks comprising in combination, a clamp, asecondary clamp rotatably carried thereby, a rod adjustably supported bysaid secondary clamp, a bracket-arm supported by said rod, and anarticle support carried by the bracket-arm, said article supportconsisting of a body portion having upper and lower end portionshingedly connected thereto for forward movements, springs carried by thebody portion for respectively engaging and supporting an end portionwhen the atter is swung forwardly, and a spring article-engaging clipcarried by the front ends of each portion.

4. A work support formed of sheet metal comprising a body, top, andbottom portions, hinges respectively connecting the end portions to thebody portion, each portion being provided with a centrally disposed slotforming consequent ears, a pin carried by the outer ends of the ears andextending across the slot, a spring rod secured to the end portion oneither side of the slot and disposed adjacent the inner wall thereof, aplate arranged within the slot and having its opposite ends respectivelysecured to the pin and the spring rod, and an article-engaging springclip carried by said plate, said clip having its ends projecting beyondthe portion to form a finger-piece.

In testimony whereof, I afiix my signature, in presence of twowitnesses.
